🔥 WASP‑121 b (Tylos) – An “Ultra-Hot Jupiter”
Atmospheric Layers: Lower layers have iron winds, middle layers exhibit sodium jet streams, and the upper atmosphere is rich in hydrogen.
Weather Conditions: Extremely hot on the day side, relatively cooler at night; clouds and chemical structures constantly evolve. The planet’s atmospheric dynamics fascinate scientists.
🌬️ WASP‑43 b – A Hot Jupiter with Daily Weather Cycles
Temperature: Day side reaches ~1,250°C, while the night side stays around 600°C with thermal clouds.
Winds: Superfast winds at 8,000 km/h, fast enough to disperse methane before it can form.
Atmosphere: Highly metallic, with silicate clouds (MgSiO₃ and Mg₂SiO₄) formed due to extreme day-night thermal contrast.
Meteorology: Clouds form on the cooler western day side; intense “exo-thermal jet streams” create dynamic weather belts.
🌊 K2‑18 b – A Potential Hycean World
Atmosphere: A hydrogen-rich envelope with a greenhouse effect; recent debates suggest the presence of dimethyl sulfide (DMS), a potential biosignature.
Climatic Outlook: Possibly a liquid ocean layer at the surface, with biochemical activity beneath making this planet a prime candidate for astrobiological research.
🪐 Titan – Saturn’s Largest Moon
Weather: Windstorms, monsoon-like climate cycles, and polar seasonal changes. Blue orb-like clouds occasionally appear in the northern hemisphere.
Rain: Not water, but methane and ethane rain; sometimes it pours heavily, as indicated by the “wet-sidewalk effect.”
Temperature: Around −183°C. The atmosphere is nitrogen-rich, with a haze layer that causes an “anti-greenhouse effect.”
Latest Discoveries: The James Webb Space Telescope and Keck Telescope have recorded signs of methane clouds and actual rainfall in the northern hemisphere.
🔭 LTT 9779 b – A Rare Ultra-Hot "Neptune-like" Planet
Temperature: Daytime temperatures exceed 2,000°C — extremely hot and highly luminous.
